Workaround for issue #89774 until it can be properly fixed. When `-gtemplate-alias` is specified Clang emits a DW_TAG_template_alias for template aliases. This patch avoids an assertion failure by falling back to the `-gno-template-alias` (default) behaviour, emitting a DW_TAG_typedef, if the alias is instantiation dependent.
